The Chicago mother of a 5-year-old special needs child is demanding answers from Chicago Public School officials after she discovered him covered in a black trash bag at school, according to the Washington Post.

In the shocking story, Nyesha Terry alleges that she discovered her son Lloyd wearing a trash bag at Wentworth Elementary School last month on multiple occasions. He is non-verbal and suffers from epilepsy, the report says.

Calling the teacher’s actions dangerous, disrespectful, and unnecessary, Terry reportedly took up the issue with the woman in question. The teacher claimed she put Lloyd in the “poncho” to prevent his shirt from getting wet (saliva often dribbles from his mouth due to his epilepsy) and to stop him from getting him sick. The school reportedly has bibs and extra clothing they could have changed him into, however, and it’s unclear why Lloyd had been isolated from the other students.

Checking in on Lloyd the next day, Terry was flabbergasted after finding her five-year-old in the exact same conditions. From there, she spoke with the principal and also reached out to Chicago Public Schools and has yet to receive an official response or explanation.

Since then, Chicago Public Schools officials called the incident “inexcusable” and have launched an investigation, writes The Inquisitir.
